Which of the following statement(s) is/are true/false? A. The following is an example of a reversible reaction N2 (g) + 3H2 (g) 2NH3 (g) B. The following is an example of a thermal decomposition reaction: CaCO3 (S) sunlight CaO(s) + CO2 (g) Correct Answer Both A and B are true

The correct answer is Both  A and B are True.

Key Points

  • N2 (g) + 3H2 (g) ----> 2NH3 (g)
    • It is an example of a reversible reaction.
  • The equilibrium shifts in the forwarding direction by increasing pressure and decreasing temperature.
  • According to the Le-Chatalier principle when equilibrium is disturbed by a change, the system will try to nullify the effect of the change to restore the equilibrium.
    • CaCO3 (S) ---> CaO(s) + CO2 (g)
  • A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.
    • These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds.

Additional Information

  • combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions are represented by equations of the following form: X + Y → XY.
  • The combination of two or more elements to form one compound is called a combination reaction.
  • Other types of Chemical Reactions:
    • Decomposition reaction: The opposite of a combination reaction, a complex molecule breaks down to make simpler ones. Such reactions are represented by equations of the following form: AB → A + B.
    • Precipitation reaction: Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. Such reactions are represented by equations of the following form: A + Soluble salt B  → Precipitate + soluble salt C.
    • Neutralization reaction: An acid and a base react with each other. Generally, the product of this reaction is a salt and water. Such reactions are represented by equations of the following form: Acid + Base → Salt + Water.
    • Combustion reaction: Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat. Such reactions are represented by equations of the following form: A + O2 → H2O + CO2.
    • Displacement reaction: One element takes place with another element in the compound. Such reactions are represented by equations of the following form: A + BC → AC + B.
